[PATCH 08/67] drm/amd/display: Remove redundant if conditions

[Zaeem Mohamed]

From: Ivan Lipski <ivlipski at amd.com>

[WHY]
Coverity analysis flagged the two if conditions in
dcn30_dpp.c and dcn401_dpp.c as DEADCODE since they
are never true, since the variable
'program_prealpha_dealpha' is initialized at 0 and
never chagnes.

[HOW]
Removed the variable 'program_prealpha_dealpha' and
the if conditions.
